There are plenty of crimes that are totally victimless for which we as a society "punish" people. I think you're right that the average person wants punishment for someone who has wronged them, but (for reasons only God knows) I think the average person also wants punishment for people that haven't wronged them at all, but just did something they think is immoral. I'll never forget seeing a neighbor call the cops on my friend who was smoking a joint in her own car. He only knew she was doing it because he was trespassing on her property. I couldn't believe someone would be such a dick to another person. I sure hope we can change cause what we do now is sick.
